The following are some common procedures that we should take action of when using a bunsen burner to ensure our safety:
1. Wear safety goggles. Tie up long hair and school ties if needed. This can lower the risk of catching on fire. Put a heatproof mat underneath the Bunsen burner, put a tripod and the beaker of water for heating on top of the burner.
2. Close the air hole. Before we start up the burner, the air hole must be closed or green flame (striking back) may occur
3. light up a match or a lighter. Put it over the chimney.
4. Turn on the gas tap, you should be able to see a yellow flame now. Remove the lighter or match and open the air hole. We should have a blue flame by now.
5. the water should start to heat up. Never touch the hot beaker with bare hands.
6. When the water is heated up to the temperature they wanted to, it's time to close the air hole and turn off the gas tap.
7. If they need to move the hot beaker, use heat protection gloves
These should be the correct procedures that they should follow in order to heat the water safely.
Hope it helps!

Answer:
<u><em>BRIEF EXPLANATION</em></u>
Photosynthesis is the anabolic process of building up glucose and making O2 from CO2 and water while cellular respiration is the opposite catabolic process of breaking down glucose by oxidizing it with O2 to get CO2 and water.
Explanation:
<em><u>MAIN ANSWER TO THE QUESTION.</u></em>
Photosynthesis is like when you’re trying to gain muscle and you eat tuna and eggs to turn it into muscle tissue. This takes energy in the form of food just like how photosynthesis requires sunlight for energy.
Cellular respiration is like when impoverished people starve for a week because they don’t have sufficient food to eat for nutrients. They have to get them from somewhere else. So the body breaks down glycogen, body fat and muscle tissue to provide the energy.
In my opinion I say 1 and 3 only or answer chose C
